Re: Rate of filtration of septage through sand filter beds and technology for septage management
Dear Mughal and all
Thanks for your quick respond.
Objective of the filtration of septage is to minimize organic loads and use effluent for further treatment for its safe reuse in agriculture purpose and also use of dried solid sludge for agriculture purpose. Filtration rate of septage can’t be increased to 5 cum / m2 per hour through natural sand filtration. It is much slower than water filtration. Septage is hydrophilic in nature. My query is simple and straight. What is filtration rate of septage through natural sand filtration under gravity per square meter of sand filter bed per 24 hours or so?
Those who are involved in septage management through sand filter beds can provide data based on the their practical experience. Any published data on the aspect would be helpful to design such system.

Dear Pawan,
The filtration rates, depth of filter bed, effective size and uniformity coefficient of sand, depend on the objectives of filtration that are to be achieved.
On water treatment side, a filtration rate of 0.2 meters/hour will remove the microbial population. This is typical of slow sand filtration. If the filtration rate is increased to 5 cubic meters/sq. meter per hour, only turbidity will be removed. This is typical of rapid sand filtration.

Dear All
For designing a sand filter bed for septage* management rate of filtration is an important aspect. If any professional has such data on septage management through sand filter beds and other technologies, may kindly inform.

* Note by moderator (EvM): We have discussed in great length what the definition of the term "septage" is here: forum.susana.org/forum/categories/53-fae...onfusing-terminology
If I understand Pawan right, he meant the entire content of a septic tank when he spoke of "septage".
