Hydrex - Ion Exchange Demineralizer
There are no ready made solutions as each water source presents its own individual characteristics and problems. The highly qualified and experienced process design engineers at Hydrex exhaustively evaluate process alternative with a view of providing the most dependable, efficient and cost effective type of treatment system for a particular project. The Choice of demineralization method and resins depends on many factors including the composition of the water to be treated, flow rate, degree of purification required, chemical efficiency, equipment cost, simplicity of operation, degree of automation desired and available space. Sometimes, Reverse Osmosis system may be recommended ahead of an ion-exchange system when Total dissolved Solids (TDS) is higher than 400~500 mg/l in order to reduce chemical consumption.
Hydrex does not make use of standard “off the shelve” systems and equipment, preferring instead to custom design, with the aid of updated computer programs, each and every demineralization system on a project by project basis. Such attention to detail ensures that our customers receive a demineralization system that:
- ensures the services and regeneration cycles are conveniently timed;
- minimizes the amount of acid and caustic consumption required by taking into account both regeneration and waste neutralization requirements; and
- requires much smaller demineralizer water storage tanks as the system cycle time is designed to closely adhere to operation requirement for process water.
The following equipment is offered as standard in most Hydrex supplied demineralizer system:
- Lined carbon steel or fiberglass exchanger tanks, fully pressure tested to meet the required codes and standard.
- PVC Schedule 80 or lined steel face piping
- Pneumatically controlled plastic or lined steel diaphragm operating valves
- Stainless steel or polypropylene inlet, outlet and regenerant distributors
- Conductivity meters with probes Flowmeters with totalizers, flowrate indicators and reset registers
- Stainless steel, liquid filled pressure indicators
- Fully assembled control panel with electronic programmable regeneration controller, monitoring instrument and annunciation system
- Ejector or pumps and corrosion resistant delivery lines for regeneration system
