Hi Susmita Congratulations ...

Hi Susmita

Congratulations on your project!! 

To choose the most appropriate design to solve the problem of liquid waste from cancer hospitals, it is necessary to collect more complete data or information to choose the best treatment, these are some of the questions that become the basis for choosing the right technology to be applied in a project.

1. Daily volume and flow rate of the waste 
2. The availability of land
3. available budget
4. Maintenance budget, if it’s any
5. Effluent targets to be achieved based on local government regulations

After the 4 questions above are answered, there will be several choices of technology that are right for the problem
1. Biological treatment technology ( SBR, extended aeration, trickling filter)
If you choose this technology, then what must be the main certainty is the area of ​​land you have, and the civil construction budget which will be very expensive, because this technology will be very successful if the land owned is very large and civil construction is right. with the presence of antibotic content and used solutions of chemotherapy and dialysis, it is necessary to add chemicals such as PAC at the primary treatment stage and the addition of chlorine at the secondary treatment stage, but to neutralize the antibotic content, it is better to continue with the addition of subsurface wetland technology, because for the case of radioctive substances can be neutralized with this technology, but still this technology will produce sludge in the reactor during the settling process, a strong and quality submersible pump is one that must be taken into account, and of course you need a filter press or screw press for solve the sludge problem, don't forget the water from the screw press must go back into the inlet tank.
2.physical-chemical technology, if you choose this technology, then the thing that will definitely happen is a large consumption of chemicals, and precision, besides that civil construction will greatly support this technology, the maintenance costs of dosing pumps and safety implementation will be a thing. Very much attention, and of course there will still be side products in the form of sludge and you need a filter press, the water from the filter press will be returned to the inlet tank.

3. electrocoagulant technology, this technology is not yet a very familiar technology, but for a capacity below 200m3 / day and you have a limited civil construction budget, also limited land, and you don't want to add difficult chemicals, then a recommendation to use this technology It needs to be taken into account, because in addition to saving construction costs, saving land and also saving maintenance costs, and requires little chemicals at the primary treatment stage which aims to neutralize pH only, of course there is an addition of a sludge treatment machine because the electrocoagulant reactor will produce quite a lot of sludge. so you need a filter press machine, the water in the filter press should be put back into the inlet tank or it can also be forwarded to the ion exchange filter, but it's better to return it to the inlet tank. This technology will usually be made in conjunction with ion exchange and absorption filters, but if there is excess land and you want to make something of aesthetic value, you can continue this technology with the addition of wetland technology, which from some literature there are several aquatic plants that can reduce radioactive content.

4. membrane technology (MBR, MBBR,)
membrane technology is used as an additional technology in biological treatment technology, MBR can be placed in a tertiary treatment stage, so that it can be used as a substitute for wetland, this technology can also continue after electrocoagulant technology and chemical physics, membrane manufacturers provide a lot of information on their products and As a rule, using this technology as a tertiary treatment you must be ready with the need for additional chemicals for CIP cleaning and maintenance.
