Mobile MaxClear™ FAQ’s

Dimensions, weight, cost, water purification and power capabilities are at a lesser amount with the Mobile MaxClear™ (MMC) but the system has the same intention as the Mobile MaxPure™.  The MMC is powered using a 900 watt solar array, the MMP is comprised of a 4 kW foldable solar array.  Unlike the MMP, the MMC foundation is comprised of a 4′ x 6′ enclosed trailer, the trailer is DOT licensed and is equipped with a military style pintle hitch for ease of towing.  The MMC can provide up to 10,000 gallons (37,000 liters) of fresh water per day depending on the amount of sunlight provided, reverse osmosis systems can provide up to 1,000 gallons (3,800 liters) of water per day.  The Mobile MaxPure™ can purify up to 30,000 gallons (113,500 liters) of freshwater per day and 3,000 gallons (11,350 liters) using reverse osmosis technology.  The MMP weighs approximately 6200 lbs. the MMC weight is 1350 lbs.

The Mobile MaxPure™ is a solar powered water purification unit comprised of a 7 ft cube containing a 4 kW folding solar array and an embedded 31kWh gel battery bank. The primary purpose of the Mobile MaxPure™ is to pump and purify existing water sources to make potable water. It accomplishes this by using both filtration and ultra violet light for fresh water applications or reverse osmosis and filtration for salt water applications. The Mobile MaxPure™ also has the ability to produce 3kW of supplementary AC power. An optional communications package and customized flatbed trailer for transportation are available.

The Mobile MaxPure™ has the capability to pump 70,000 – 100,000 gpd of water purposely for flood dewatering or irrigation, the MMC has the same capability but at a lesser flow rate.

The Mobile MaxClear™ (MMC) can pump and purify up to 7 gallons per minute (GPM) or 420 gallons per hour (GPH) from polluted freshwater sources.  On an average of 5.5 hrs of sunshine per day, you could purify 2,310 gallons a day.  Running on the provided diesel generator at night, The Mobile MaxClear™ can pump and purify up to 10,000 gallons per day (38,000 liters) (GPD).

Creating potable water from brackish water source, the MMC can purify up to 1,200 gallons (4,500 liters) of water per day, additionally using reverse osmosis technology, the Mobile MaxClear™ can purify up to 1,000 gallons (3,800 liters) of water per day all depending on the amount of sunlight offered.

If the water purification system is bypassed and the Mobile MaxClear™ unit is only pumping water (no purification) it can used to dewater flooded areas following a natural disaster or for irrigation purposes.

The Mobile MaxClear™ trailer is a 4′ x 6′ enclosed cargo trailer customized and designed by WWST.  The enclosed trailer is a DOT approved single axle trailer, rated for 2,000 lb GVW.  The trailer comes standard with a military style pintle hitch and opens from the rear side.

The Mobile MaxClear™ weight is approximately 1,350 lbs. (615 kg). *Weight of solar array not included.

External dimensions: 13.5 ft. long x 6.1 ft. wide x 7.2 ft. high (4.1m x 1.8m x 2.1m)

The MMC must be placed on a solid, level surface. This may be directly on the ground or on a concrete pad, depending on your site conditions. Ideally, the deployment location is no more than 50’ from the water source. The water source should be tested to ensure sufficient flow and to identify the contaminants present.

The Moblie MaxClear™ includes a standard 5.4 kWh embedded battery bank consisting of sealed, gelled electrolyte, batteries. Since they are sealed, they are “maintenance-free,” they cannot leak battery acid, and no fumes are produced. They are certified as “non-spillable and non-hazardous” and can be shipped by air without special packaging containers.

Battery life is a function of several factors: How often the batteries are discharged (less is better); the depth of the discharge (shallow is better than deep discharges); the ambient temperature the batteries operate in; and the number of years in service. The battery manufacturer provides a one year warranty regardless of where the unit is located. Battery packs will need to be replaced on the average of every five years.

The unit is warranted for one year (365 days) from date of shipment for any manufacturer or component defects. Once the unit leaves the WorldWater loading dock, any damage that might be incurred during transportation is the responsibility of the purchaser. The unit is packed securely.

Pass-through warranties from some of the component manufacturers are: Batteries are warranted for one year. Charge controller, inverter/charger, and system controller are warranted for two years. The solar panels have a 25 year design life.

No. All necessary items are included, installed on the MMC.  A one year average supply of filters and other consumable parts are included in the original purchase price of the Mobile MaxClear™ unit.

In addition, the unit is tested at the factory as a total system with the batteries, filters, pumps and electronics, completely assembled. The only onsite assembly is plugging the extension cord from the submersible pump into proper receptacle on the Mobile MaxClear™.

Typically within 15 to 30 minutes after positioning the Mobile MaxClear™ near the water source, the unit can be operational and producing potable water.

Both of these technologies remove pathogens, bacteria, viruses, dissolved solids, organics and salts but the level of contaminants removed is the main difference.

Reverse osmosis (RO) semi-permeable membranes have smaller pore sizes than ultrafiltration (UF) membranes. Typically RO filters have a pore size of around 0.0001 micron level, UF has a pore size of around 0.1 micron.

RO systems use a lot more energy to force the untreated water through the membrane than UF.

Parts Per Million (PPM) is a measure of concentration. When dealing with RO systems, PPM is important. Usually with salty water, the majority of the PPM numbers are from sodium and chloride (everyday salt). Along with other items in the salt water such as magnesium, calcium, potassium, —all of these become the Total Dissolved Solids (TDS) measured in mg/liter.

The Brackish Mobile MaxClear™ can process source water with a TDS level of up to 10,000 PPM. The Seawater Mobile MaxPure™ can process source water with a TDS level of up to 45,000 PPM.

No, it is possible to find “salty/brackish” water inland, where the ground water is located in soil that is high in salts. This is why, ideally, it is a good idea to test the water for TDS of salts before ordering the Mobile MaxClear™.

The presence of dissolved solids may affect its taste. The palatability of drinking water in relation to its TDS levels is as follows: excellent, less than 300 mg/liter: good, between 300 and 600 mg/litre: fair, between 600 and 900 mg/liter: poor, between 900 and 1,200 mg/liter: and unacceptable, greater than 1,200 mg/liter. (Guidelines for Drinking Water Quality, World Health Organization, 3.4.16)

Freshwater-source Mobile MaxClear™ purification systems are not suited for brackish water and brackish water purification systems are not suited to handle sea water applications.

The Mobile MaxClear™ freshwater system will remove waterborne infectious microorganisms such as protozoa, parasites, bacteria, fungi, algae, and viruses. Additionally the system will reduce levels of mercury, lead, heptachlor, chlordane and total dissolved solids. Finally, the system utilizes activated carbon to improve taste and smell.

Reverse osmosis systems treat for each of the contaminants that the freshwater purification filtration treats, using reverse osmosis membranes. These reverse osmosis membranes also effectively remove dissolved solids such as salts, as well as viruses, bacteria, fungi, algae and protozoa.

The table below lists many common microorganisms and dissolved solids removed by the reverse osmosis purification process in addition to the removed contaminants shown above.

If you have other contaminants in your water please consult a WorldWater representative to determine the purification customization that may be needed to create purified water from your source.

The frame of the Mobile MaxClear™ is consisted of stainless steel and aluminum to allow operation for many years without rusting.  The deck material is synthetic wood to prevent deterioration. Additionally, all control electronics are marine grade – designed for salty, humid, environments and are sealed from the elements.

There are some conditions that would limit operation of the Mobile MaxClear™. If high winds are encountered (above 60 mph) the solar array should be stowed. The Mobile MaxClear™ should not be operated in below freezing conditions as the water system components will freeze. If the unit is to be stored in below freezing environments the entire water system must be drained and dried. Operation at latitudes higher than 40º will result in less than optimum collection of solar irradiation.

The solar array is rated against breakage for the impact of up to one inch hail stones. It is unlikely that a solar panel would suffer breakage during normal operating conditions. Glass breakage in solar panels used worldwide in mobile applications is extremely rare.

If the glass does break the panels will still be producing solar electricity, though at a reduced efficiency. Damaged solar panels should be replaced to allow the unit to operate at peak efficiency. Replacement panels are available for purchase from WorldWater & Solar Technologies, Inc.

Yes. Even on cloudy days there is a significant amount of solar energy collected by the MMC solar array. Additionally, the on-board battery storage provides for night-time water purification and power generation. During periods of cloudy weather the Mobile MaxClear™ is capable to continuously run with the additional support from the standard battery component.

No. When the MMC is first positioned, it should be placed so the solar array is facing south when north of the equator, and facing north when south of the equator. The solar array can be set at a horizontal position (at the equator). Once set, the array needs no further adjustment but minor maintenance is needed as the panels are flat so water, snow etc. can accumulate.

Yes. The MMC inverter system generates a pure sine wave which is ideal for powering critical electronic devices.

Yes. The Mobile MaxClear™’s 1000W inverter and 110 VAC allows for ample power to operate saws, air compressors, power tools, and other electrical appliances.
