Pre-treatment plays a very important role in efficient and safe operation of the purified water generation system. The pre-treatment is designed with highest care using conservative design approach. The raw water pre-treatment units are modular and designed according to incoming water characteristics.
Typically the raw water pre-treatment units include media filtration, softening and Ultra Filtration Unit as standard feature. These compact and modular treatment pre-treatment systems are engineered for robust performance ensuring maximum availability even for most demanding applications. The pre-treatment system is built to meet any capacity requirement.
The MGF works on principle of retention and removal of physical impurity in a graded manner through Voids of the filtering media. It is a kind of a deep filter bed with adequate pore dimensions for retaining both large and small suspended solids and un-dissolved impurities like dust particles. This arrangement produces a filter bed with adequate pore dimensions for retaining both large and small suspended particles. This filter performs at a substantially higher specific flow rate than conventional filters.It is also a low cost pre-treatment system for ion exchangers (deionizer and softener) and membrane systems such as reverse osmosis etc. With high throughputs, high dirt-holding capacity and capacity to reduce turbidity and TSS (< 5ppm) from water, it protects ion-exchange resins and membranes from physical fouling due to suspended impurities present in the water.
HERACLES Ultrafiltration Systems are designed for removal of suspended solids including bacteria, endotoxins and high molecular weight molecules. This level of filtration offers many advantages, including reduced fouling of any downstream RO membranes and lower endotoxin burden on downstream equipment.The membrane filters can be provided individually or as part of a total water treatment solution. The control system for the membrane filters can be dedicated to the filter system or part of a total water system. Hollow-fiber membrane construction allows reverse flow backwash cycles to remove the accumulation of filtered solids.· Pre treatment Ultrafiltration
Softening is an ion exchange process used to remove ions from the water that contribute to alkaline scale formation, primarily calcium and magnesium. As water containing these ions passes through the softening resin bed, the ions are exchanged with sodium ions residing on the surface of the resin. When no more sodium ions are left for this exchange process, the resin must be regenerated. Regeneration is accomplished with a brine solution of sufficient strength to cause an exchange between the sodium ions in the brine and the calcium and magnesium ions on the resin. Once regeneration is complete, the resin is ready to begin the softening cycle again.
HERACLES Water Softeners are designed for the removal of hardness, ammonia or both. The softeners are designed based on your effluent water quality required and the feed water analysis. Softeners can be provided individually or as part of a total water treatment solution. The control system for the water softener can be dedicated to the softener or part of a total system. Softener systems are designed specifically for your application using either fiberglass, PVC, lined carbon steel or stainless steel in the materials of construction.
