CONCLUSION

Parameters affecting the operations of the WTP are turbidity, ammonia, organic.

The main problem in Buaran WTP is turbidity. Prasedimentation should be done in order to reduce the turbidity of raw water.

The whole society should care about the environment by not throwing the garbage into the river.
