Hi Hossein. My company geos has a specialty in developing automated water loops to control variables and readings. I Think the group has posted good data concerning to your request. In my opinion you should implement that posted above and a system of control with data log and alarms of behavi ...

You must design the loop to maintain  1 m/s at the end. The best option is control de pump with a VFD and a flowmeter at the end of the loop. After the RO plant you must install a degassing system or a contactor membranes (Liquicell) to remove the CO2. You must install a ozone gene ...

Please consider checking pH of the effluent and influence. But as you said, Iron could be the reason behind the coloration. I suggest you add air or some other oxidizing agent to your waste water source if you have not done it yet. This issue should be minimized with the oxidation process. ...

Pretreatment of effluents consists of screening, flow equalization, neutralization, and air flotation (to remove fats and solids); it is normally followed by biological treatment. If space is available, land treatment or pond systems are potential treatment methods. Other possible biological tre ...

The effect of oil on filtration by sand beds will be disastraous. The oil will form a solid film with individual sand particles and will not allow filtration. But, you are concerned about oil leakage from equipment. If you mean the mechanical equipment as per the WTP design, I don't think yo ...

Hi Nilam. If you have water treatment works using iron based coagulants then these can be used to help overcome septicity. Typically the coagulants will be taken from DAF plants and considered a waste sludge to be disposed of. They still have good sequestering potential and can help keep H2S pro ...

Unless there is some particularly active trade effluent in the sewage the reason for septicity is due to the time stoed. Assuming the rising main has been sized correctly then this can generally only be due to a combination of the length of the main and the rate of inflow to the pumping sta ...

If you have any simple rising mains, rather than ones with more complex vertical profiles, you might try using a compressor to add air to the main. It also keeps the main clean but there can be a problem at the receiving end as the unused nitrogen has to escape to atmosphere.

Adding the Archaea species to these stations  will eliminate all odors, reduce the affluent into dissolved bio nutrients, increased oxygen content, and elimination of all pathogens. less bio solids to transport, less to be treated, elimination of chemicals and their transport to offsite loc ...
