The application of this filter separator is the removal of solid impurities and Precipitiational

stick down to them and run down. On the way downwards they meet other droplets and agglomerate to larger droplets which are flowing down inside the fiber glass layers also. To achieve the high separation efficiency the gas muts flow from the inside to the outside of the coalescer elements. If no solid particles are present in the gas stream the replacement of the elments is not required.
Every community produces both liquid and solid wastes and air emissions. The liquid waste-wastewater- is essentially the water supply of the community after it has been used in a variety of applications. From the standpoint of sources of generation, wastewater may be defined as a combination of the liquid or water-carried wastes removed from residences, institutions, and commercial and industrial establishments, together with such groundwater, and surface water as may be present.
When untreated wastewater accumulates, the decomposition of the organic matter it contains will lead to nuisance conditions including the production of malodorous gases. In addition, untreated wastewater contains numerous pathogenic microorganisms that dwell in the human intestinal tract. Wastewater also contains nutrients, which can stimulate the growth of aquatic plants, and may contain toxic compounds or compounds that potentially may be mutagenic or carcinogenic. For these reasons, the immediate and nuisance-free removal of wastewater from its sources of generation, followed by treatment, reuse, or disposal into the environment is necessary to protect public health and the environment.
Wastewater engineering is a branch of environmental engineering in which the basic principles of science and engineering are applied to solving the issues associated with the treatment and reuse of wastewater. Selection of wastewater treatment process or sequence of processes depend on a number of factors including
1- Characteristics of the wastewater, e.g., BOD, % of suspended solids, pH, presence of toxic materials;
2- Required effluent quality;
3- Cost and availability;
4- Consideration of a possible future upgrading of water quality standards.
In the following chapters, brief descriptions of treatment processes will be presented.
The hydrogen-ion concentration which is an important quality parameter of both natural waters and wastewaters. The concentration range suitable for the existence of most biological life is quite narrow and critical (typically 6 to 9).So, wastewater with an extreme concentration of hydrogen ion is difficult to treat by biological means, and if the concentration is not altered before discharge, the wastewater effluent may alter the concentration in the natural waters. For treated effluents discharged to the environment the allowable pH range usually varies from 6.5 to 8.5.
BOD (Biological Oxygen Demand)
Quantity of oxygen required for oxidation of biodegradable organic matter present in the water sample by aerobic biochemical action.
ThOD (Theorical Oxygen Demand)
Stochiometric amount of oxygen required to oxidize completely a given compound.
COD (Chemical Oxygen Demand)
The amount of oxygen required to oxidize the organic fraction of a sample which can be oxidized chemically using dichromate in an acid solution.
TOC (Total Organic Carbon)
The total amount of organic carbon in an aqueous sample.
TS (Total Solids)
Total solid contents of wastewater varying from rags to colloidal materials.
TSS (Total Suspended Solids)
A fraction of TS in the wastewater which is settleable. A filtration step is used to separate these suspended solids and the amount of which depends on the pore size of the filter used for the test. Filters with normal pore sizes varying from 20 to 45 micrometers have been used for TSS measurement.
TDS (Total Dissolved Solids)
Those solids that is comprised of colloidal and dissolved solids and pass through the filter.
TVS (Total Volatile Solids)
Those solids that can be volatized and burned off when the TS are ignited.
VSS (Volatile Suspended Solids)
Those solids that can be volatized and burned off when the TSS are ignited.

Increasing the lifespan of membranes used in operational systems is very important, and this is made possible with the good maintenance and management of the systems.
The NIKAN Company has developed an after-sales-service unit in order to help users of RO water treatment systems, to decrease their maintenance costs and expand the lifespan of RO membranes.
This new unit provides the following services to the owners of water treatment systems:
Ongoing and regular inspections of the water treatment systems by experienced experts.
Instructing and training of personnel while the system is being installed.
Chemical washing and maintenance of membranes.
Providing the necessary spare parts.
Making available reports on the condition of water treatment systems, problems, and solutions to the client.
In view of the fact that our aim is the satisfaction of both clients and contractors, NIKAN has put the after-sales-service unit into operation. After finishing a project, NIKAN, apart from providing general services, provides ongoing advice, parts, and materials. Regular inspections of operational units are also carried out to examine the machinery and provide the necessary services.
NIKAN Company, thanks to its group of experienced managers and engineers who all have valuable experience working on big industrial projects in Iran, has started implementing industrial projects in MC form.
NIKAN uses experienced and specialized technical personnel, and competent advisors and contractors, to assume responsibility for managing a wide variety of executive projects, structural projects, installing machinery, and also purchasing and transporting necessary materials. These tasks may be subcontracted to trusted companies to ensure contracts are fulfilled with the best possible quality, deadlines are met and projects remain within budget.
