Energy Recovery Devices manufactured by FEDCO, USA. Is the most innovative and cost effective mechanical device, which is a must for energy recovery in SWRO and for inter-stage boosting in BWRO.

The Hydraulic Pressure Booster or HPB is a fully self-contained brine energy recovery device for seawater and brackish water systems. With over 850 units in field service, the HPB has earned a reputation for reliability, ease of operation and most importantly as the best value in energy recovery to day.

The HPB generates a pressure boost in the feed stream ranging from 20 to 40% of the total membrane requirement. The unit is entirely energized by the brine stream. The brine and feed provide all lubrication and cooling. The HPB includes an integral valve for brine pressure regulation.

How the HPB Save Energy And Capital Costs

The HPB is installed between the HP pump and the feed inlet to the membrane.

The HPB produces up to 50% of the membrane pressure requirement, thereby, reducing the size and energy requirement of the HP feed pump and motor and motor starter.

GMS provides service to its customers through evaluation of Chemicals in use and studying the problem faced in a particular scenario. Based on its evaluation GMS advices usage of Generic chemical or a particular formulation which ever is effective and cheap. GMS has also solved problems in many big installations in India where the problem faced by the customer was purely due to improper usage of branded chemicals or due to lack of understanding of the problem it self. GMS supplies High performance chemicals for cleaning, scale prevention, bio growth retardation, etc. These are extremely efficient in the control of fouling, removal of scales and flux restoration. These tailor made chemicals have been proven to be superior to generic chemicals, in some cases, besides being compatible with membranes.

Generally surface aerators are used in the secondary effluent treatment plant for oxygenation. Typically a surface aerator transfers 0.9 to 1.0 kg oxygen per HP of motor per hour. The design and location of surface aerators create anaerobic pockets in the aeration tanks besides frothing at the surface of effluent which results in very low or no oxygen transfer. The submersible aeration system is extremely useful for aeration due to very high oxygen transfer efficiency as against surface aerators/ diffused air systems. Typically the oxygen transfer efficiency varies between 1.6 to 1.9 Kg/HP/Hr. The other advantages are no foundation, no noise, no sprays, low maintenance, thorough mixing, flexibility in layout & space saving.

GMS supplies micro filtration system based on ceramic membrane with builtin backwash systems for various applications such as bio-mass separation, Sterile filtration, fermentation broth clarification, cell harvesting, Solvent purification, precious metal recovery and enzyme concentration.

Some of the benefits are better permeate quality, higher flux and lower operating cost. It has long life due to high resistance to temperature, pressure & solvents. It is sterilizable by steam as well as chemicals. GMS has supplied many Ceramic MF systems for pretreatment in RO plants for effluent treatment and Zero discharge. The first Juice clarification system based on Ceramic MF in India has been supplied by GMS.
