Walchem has introduced the Digital EZC Series Metering Pumps, the latest addition to its E Class pump line. The new pumps are solenoid-driven, diaphragm metering pumps with a maximum capacity of 6.7 gph and a maximum pressure of 150 psi. The high speed, fixed stroke length design makes the pumps an economical solution for applications requiring low cost but high turndown capabilities. The units pump at 360 strokes per minute, reducing the chemical slug feeding found in slower metering pumps. The digital controller has three pushbuttons for speed adjustment and provides an IP65 solution for harsh environments. For installations with restricted access, the digital controller can be mounted remote from the pump.
Micro Dist® from Lachat is designed to avoid the costly problems of using expensive, fragile glassware, fume hoods, and clean up when distilling samples for wastewater analysis. The system distills up to 21 samples for sulfide, cyanide, methylmercury, and ammonia in 30 minutes, phenolics and tritium in 90 minutes. The system can handle many sample types, even if the sample is a sludge or has a high level of suspended solids. The USEPA has now approved Micro Dist analysis for NPDWR monitoring of cyanide and recommended approval for NPDES monitoring. The unit consists of only two pieces, a collection tube with a porous membrane and a sample tube, which are disposed of after use. The press fit joint between the two does not leak, a potential problem when using glassware.
The ecoSep® Below Grade Oil/Water Separator from Royal Environmental can help keep water clean from oil contaminates. The unit permanently separates oil from water and allows virtually no oil emulsion formations to develop. Independent testing demonstrates that its high-efficiency separation of free oils and hydrocarbon-laden sediment exceeds today's environmental standards. The units can be designed for use in point-source and industrial stormwater applications. No external energy supply is needed; there are no electrical parts, only mechanical and stainless steel components. The units allow for access to all major components for cleaning and maintenance.

Mobile storage tanks
Terracon offers the HLT Mobile Water Storage Tank. These seamless one piece molded linear polyethylene construction tanks are designed for durability. Molded-in legs ensure structural integrity and stability. The tanks can be used to feed pressure washers, concrete saws, or any other mobile application that requires water away from traditional supplies. The tanks range in capacity from 30 gallons to 525 gallons. Painted steel bolt-down anchor straps are available for all sizes.
USFilter Kruger Products' Actiflo system is a compact, high-rate, physical-chemical clarification process that uses microsand along with lamellar settling to enhance flocculation and clarification. By using microsand as a seed for floc formation and clarification, the process is up to 20 times smaller than conventional processes. Furthermore, the sand allows for more effective removal of solids, organics, metals and pathogens. The sand also stabilizes the process during sudden fluctuations in raw water quality.

Poly Processing offers the Safe-Tank® storage and containment system, the tank within a tank. The high density crosslinked polyethylene tank alleviates the need to build large high maintenance concrete containment areas. In the event of a spill, the system's all-in-one design features a protected containment area that will isolate reactive chemicals, all within the footprint of a standard vertical tank.

Seawater treatment membranes
In response to demand for a less cumbersome and costly way to treat seawater for production of industrial process water, GE Osmonics has engineered the new Seasoft™ membrane elements. Using Seasoft nanofiltration (NF) elements as a pretreatment step reduces the hardness of seawater by more than 95 percent. This hardness reduction enables reverse osmosis (RO) plants to operate at lower pressures and higher recoveries. By providing a more purified feed to subsequent processes, the new membranes have facilitated a 25 percent increase in overall productivity while reducing pressure requirements by 17 percent. The membrane elements are available in a standard 8 in. diameter and 40 in. length.
Severn Trent Services offers the Advance® PDS precision dosing system as a pre-assembled and pre-wired packaged system designed for chemical injection. The system features corrosion-resistant materials for all wetted components in the single- or multiple-pump system arrangement. The system, effective across a range of applications and operating conditions, features integrated controls for automated system operation, alarm indication and system shutdown. Optional remote alarms for low tank level, tank mixer and shutdown are also available.

Odor Control Co. is now offering free lab testing of malodor samples. The company will test the sample and formulate an odor neutralizer that will eliminate the odor problem. Its lab helps customers determine the best molecularly structured odor neutralizer for their waste. A wastewater treatment plant might identify hydrogen sulfide as their primary source of odor problems. However, there might be additional, less detectable or identifiable odors being emitted into the air. Raw sewage has pesticides, food preservatives and other chemicals that add odors into the air. As an added service, the company will provide and pay for a sample testing kit and all related shipping and testing charges.

Atofina Chemicals reports that in recent cavitation erosion resistance tests, coatings of Rilsan® PA-11 fine powder were shown to be three times better than 316L stainless steel. In other cavitation tests, Rilsan coatings were over 75 times more cavitation erosion resistant that the best fusion-bonded epoxy coatings. All tests were conducted and reported by an independent testing laboratory. The fine powder coatings meet AWWA standard C224.01 and several different colors are approved for potable water use under NSF-61. They are easily applied using conventional powder coating methods and are available worldwide.

Sanitary butterfly valve
Gemco a manufacturer of equipment for solids processing industries, has manufactured its line of Spherical Disc Valves since the 1930's. While this valve offers a full port opening, self-cleaning seat and long life, it does require a high profile related to its diameter. For space restricted applications, the company now offers a low-profile Butterfly Valve. Measuring only 1 1/2 inches in thickness, the SB valve can fit in the tightest spaces.

Munox® XL-Plus, available from Osprey Biotechnics, is patented biotechnology using natural, live bacterial cultures for degradation and control of fats, oil & grease (FOG) prevalent at wastewater collection and transfer points. Treatment with the product is a safe, cost-effective method of eliminating troublesome organics from municipal treatment systems. Using the new grease treatment program, municipalities report 90% to 100% reductions in grease buildup at previously troublesome locations. The product recently gained recognition by EPA's Design for the Environment partnership program, the first involving an industrial cleaner/degreaser that bioremediates.

Thern power winches are a versatile alternative to complicated overhead hoist systems. The winch can be mounted upside down to a support beam to raise and lower filter screens for periodic cleaning. Once out of the channel, the screen is held in a cleaning position by a tie-off cable. There are several mounting options to accommodate special plant considerations. Special rated motors and controls provide protection in corrosive or explosive environments.
Gas flow equalizer
USFilter has introduced the new Equa-Draw™ System engineered by Wallace & Tiernan Products. The system eliminates waste and reduces labor associated with traditional manifolding of vacuum regulators commonly used for water treatment gasses, such as chlorine, sulfur dioxide and ammonia. The patent pending system equalizes the gas that flows from several connected gas containers — all under vacuum for safety. The design eliminates the need for manually balancing the flow rates from each individual vacuum regulator. The modular system can link up to six gas containers, either 150 lb. cylinders or one-ton containers.
