Wastewater recycle and reuse is an important way for water conservation, which makes great economic sense. After making significant investments in pollution control plants, it will be very cost effective to further treat the effluent for various reuses. This will not only lessen the impact of wastewater discharges on polluting the environment, it will also preserve the “virgin” water for other water users that require higher quality. Wastewater reuse is becoming an increasingly important source of water. The volume of sewage effluent is increasing and safe disposal can be difficult. The use of reclaimed wastewater for irrigation is the obvious solution.
Benefits of wastewater reuse:- The water and nutrient content in treated waste water can be very useful for agricultural purposes.
- Wastewater reuse contribute to National Development.
- It provides a strong motivation for effective O&M thus controlling the Environmental pollution
- It enables municipalities to generate revenue by selling their sewage.
- Provides opportunities for privatization
- Industrial reuse of cooling systems, boiler feed, process water
- Reuse in agriculture and horticulture, watering of lawns, golf courses
- Ground water recharge for augmenting ground water resources for downstream uses or for preventing saline water intrusion in coastal areas
- Fire protection
The Headworks MBBR/IFAS biological system offers a novel and dependable solution to wastewater treatment, recovery and reuse when non potable water quality is required, e.g. for field irrigation, industrial use, wash water, flush water etc The IFAS/MBBR technology offers flexible solutions to multitude of biological process upgrade applications such as nitrogen and phosphorus removal, treatment capacity increase and wastewater reuse.
The upgrade to IFAS or MBBR often consists of simply adding carriers and screens to existing basins and can therefore be completed in a cost-effective and timely manner without major civil engineering requirements and no requirement for additional land. PLC based control system optimize IFAS/MBBR process performance by minimizing energy and chemical cost.
The systems key benefits contributing towards our goal to reuse wastewater is:- Minimal reactor volume required for retrofits, due to the effectiveness of the media, the process offers one of the only methods of significantly increasing plant treatment capacity, include hydraulic and process capacity, thereby allowing increasing production, with very little expansion of the existing biological system. This then allows a modular approach to be adopted down stream by providing additional treatment/filtration by using sandfilters, disinfection (UV, ozone or chlorination) or Membrane treatment to allow the increased production of wastewater reuse.
- Headworks MBBR system is ideally focused keeping in mind future demands. Once the minimal infrastructure construction for the MBBR process are complete, one of the main parameters defining the treatment capacity is volume of biomass carriers inside the reactors. Carriers can be added on demand, and the treatment capacity is expanded proportionally. This allows both timely adaption to changing requirements, such as seasonal fluctuations in wastewater quantities, and allows for reduce capital expenditure as and when required, so that investment in the upgrade is done only when needed and not years ahead.
