For Best Results Select A Proper Site Before Setting Effluent Treatment Plant

It is due to industrialization and boom in technology, there is a boom in real estate, for commercial as well as residential purpose. But, here, there need a lot of planning before setting up a residential or commercial area. Apart from roads, lights, and other related issues, laying down a well-planned sewage network comes in top of the list of basic requirements for such setups.

While picking up a construction site for Effluent Treatment Plants one has to evaluate certain factors that can determine suitability factor of the selected site for this purpose. Elements like land use, climate, geology, topography besides soil character and hydrology are the deciding factors in setting up such solutions. Physical characteristics as the depth at which rocky layer exists, besides the number of other geographical issues regarding soil, play a dominant role that are to be considered before setting up a sewage network of the area. The rocky layer should be deep enough so that the laying of sewage pipe network can be facilitated over a considerable distance. When these factors taken in account waste water can easily passes to the treatment site.

These treatment plants can also be constructed on sloppy terrains, if the slope permits, but ensure to keep structural requirements in minds prior to the commencement of the project. Solution providers with varied and vast experience in their sleeves can built multiple tiers, if there is scarcity of land where this project is to be established. Even the waste or interstitial space lied in between two premises or other utility plots can be used to develop these treatment plants.

It is better to reduce the usage of land for such purposes as we all know that God has stopped creating land long ago. Keeping this context in mind, let me tell you, that technologies or solutions that cover large area of land segments (like Constructed wetlands) will have to adopt newer technologies for this purpose. Apart from land, there are other reasons too for adopting newer and innovative solutions.

As an industrialist or as a real estate developer you must all take into account aspects as thickness of soil, as well as the amount of clay/sand plus the penetrability of the soil, beforehand setting up a treatment plant. One should also consider the level of load bearing capability of the soil (at full hydrological load), taking in account the kind of structure that has to be constructed for the plant. There are some faces that can make a site for setting up of treatment plants highly unfavorable. Any area that is located near or besides a water recharge zone, wells that are used to draw deinking well and irrigation purpose, water recharge zones, wetlands or the regions where the water table varies as per the season, and the areas that are often submerged by floods.

Factors Affecting the Quality of Effluents in Effluent Treatment Plant Design

The quality of effluent in your treatment plant is of great importance. The characteristics of the effluent determine the important factors that are related to it. The biological, chemical, and physical properties that affect the quality of effluent must be considered while designing the treatment plant. Some of the parameters that need to be considered are:

• Size of the effluent treatment plant: You need to decide how large the effluent treatment plant needs to be.  So that you get the hydraulic computations right, you need to compute the estimated effluent inflow in to the plant as well as the size of the conveying pipes and effluent channels.

• Properly estimate the effluent inflow: You will also need to incorporate the design in such a way that the inflow of effluent can be accounted for and built scalably in the foreseeable future.

• Estimate the seasonal variations: You will also need to estimate the seasonal variations in the size of the inflow. Moreover there could be larger inflows during the day compared to the night. What’s more, the inflow is likely to be greater during the rainy season. This inflow needs to be stabilized or made near constant so that the treatment process downstream remains functional.

• Use of equalization tanks and ponds:  Such tanks and ponds offer additional benefits. In many cases, toxic substances present in the effluent can affect the effluent processes. Thus the toxic effluent can be reduced by diluting it in equalization ponds with the help of effluent that is composed of lesser toxins.

• Capability to withstand shock loads: While designing the plant, you should also consider the fact that it needs to be able to withstand the shock loads during festival seasons such as Christmas and New Year. The effluent load can also increase during various festivals. 

• The physical characteristics of the effluent: You need to consider the physical characteristics of the effluent while designing your plant. This includes the colour of the effluent, the constituent solids, its temperature, and even odour. This also means that the presence of suspended solids indicates the poor quality of effluent that makes the treatment difficult. 

• What about solid material: Solid particles can consist of a variety of material such as grease or floating debris. This indicates that the effluent has not been effectively treated earlier. 

• Other factors: Other factors include turbidity of effluent, quantity of silt present and also the temperature of the effluent. An unfavorable temperature can also impair the necessary biological as well as chemical processes. 

To conclude, it is essential that inorganic chemicals, heavy metals, toxic metals, etc. need special treatment processes. The scarcity of water is also important factor that needs to be considered. If you risk contaminating ground water or a nearby running stream or river, then you will need to consider better techniques for effluent treatment plant design.
