Sewage management has been of a main concern of communities when planning their towns. During the prehistoric years the archaeological study exposed the motivation of people to develop “clean” residential network.
In the modern age, the disposal of waste water and sewerage in natural recipients such as streams, seas etc. are not adequate, and hence the advanced treatment and reuse has become necessary to compete with the modern trend. Yet they have managed to irrigate their fields through localized water harvesting methods. During the 20th century the key target of sewage treatment was the removal and treatment of subside and floating particles, the organic matter BOD and total suspended solids TSS and pathogen microorganisms. But the trend has changed in the 21st centaury by giving more focus on environmental protection and motivation in treating the sewerage and effluence with new concept and technology. The production of fresh water by RO plants has become very common.
The increasing Earth’s population, the jumbo metropolitan cites, global warming, carbon footprint, high water demand and drafts together with the aging infrastructure of last century are the challenges and opportunities in the modern age.
The existing sewerage and effluent plants based on well known biological method, which serves the international community, whereas now the time has changed by the use of the new technology by ELECTROLYSIS application.
Comparing the ELECTROLYSIS system with biological treatment, following are the features:
- Electrolysis has a smaller amount moving parts and unit process as well.
- It requires no need to maintain MLSS and PH.
- It is temperature self-regulating and it starts and stop operation at its desecration.
- Since it is toxicity tolerant, there is no need to revive bacterial.
- Electrolysis creates less green house gas (GHG) and does not deplete atmosphere oxygen.
- It does not cause stream eutrofication and in operation it creates no odor and noice.
- Electrolytic plants treat laundry waste and eliminate oil and grease and hence they do not need oil and grease traps.
- The recovered treated clean water has better functionality and there is no need of external chemical disinfection.
- Solids from electrolytic plants are less, more stable and less bacteria count and therefore easy to manage.
- Electrolytic plant has small footprint (300 m3 area for 1000 m3/day) and need less civil works.
The noiseless and odorless features allow the installation of electrolytic treatment plants within the residential areas.
Instead of large centralized plant, a town can facilitate with many peripheral units. This parameter reduces the project cost by allowing the recycling and reusing of treated water within the communities.
Futures of Electrolytic Process:
Electrolysis is purely non biological. This technique involves the passage of electricity through water or effluent to be treated. The electric current destabilizes the dissolved particles and alters the charge on suspended matter, permitting electro-coagulation, agglomeration, electro-flotation and alleviate their removal.
Electrolytic treatment removes Organics, Suspended Solids, Turbidity, Algae, Odor, Fats, Oil, Grease, Heavy Metals, Phosphate, Color and Disinfects Water.
Electrolytic plants are convenient for residential areas, hotels, industries, farms etc.
Nowadays more and more high-tech constructions as Oil and Gas offshore platforms and new mega projects specify only Electrolytic technology for sewage treatment and water recycling.
The recycled water can be used for toilet flush, industrial use, irrigation and for firefighting.
