Why Wastewater Screens Are Essential for Effective Treatment Systems

Wastewater screens are the essential step in the filtration and purification system in the water treatment plants of the latest generation. These pulsing devices are to be installed to extract large solids like plastics, rags and debris in their raw waste water before they are filtered into secondary waste water treatment procedures. Inadequate upstream screening may lead to eventual clogging and malfunctioning of downstream equipment such as sewage grinder pump systems, which not only become expensive to repair, but also become inefficient.

Wastewater screens can be classified in several types such as coarse screens, fine screens and micro-screens and they are used to screen certain particle sizes. Screens are useful in preserving the integrity of the wastewater biological treatment systems, as they degrade the organic waste by microbial actions, by efficiently removing the non-biodegradable materials very early in the process.

Interdependence of wastewater screens and biological treatment is important. Screens also provide that the only organic, curable material gets to the aeration tanks or bio-reactors and maximize the efficiency and service life of micro-organisms utilized in waste stream biological wastewater. With no interference of solids on the activities of these microbes, the system becomes more efficient in lowering biochemical oxygen demand (BOD) and also in eliminating nutrient such as nitrogen and phosphorus having their activities.

The pre-treatment stage can also be improved with the addition of a sewer grinder pump system in municipal sites and the industrial environment. These pumps reduce other remaining solids down into fine particles to make flow easier and decrease the chances of blockage in small pipes or sensitive parts of the treatment mechanism.

As a final point of note; the combination of high-quality wastewater screens and biological treatment processes, along with grinder pump installations, result in a very durable and effective solution to wastewater management. Complex pre-treatment that these plants do to their facilities not only safeguards their equipments but also renders them environmentally friendly, hence economically and ecologically responsible.
