1  Project Design and Development

 

A. Feasibility Study:

A feasibility study is performed before any project is undertaken. The feasibility study covers the following areas:

1 To elucidate if certain effluent treatment step is viable
2 To ensure that the treatment approach is an economic model

B. Treatability Study:

With different types of industrial applications in the modern world, so do the differences in the effluent generated by each industrial application. There is always no one stroke application in the treatment methodology that is adapted in standard waste water treatment units like that in a Refinery or a petrochemical industry. Even within these industries, the type of raw materials has demanded new processing technologies and generate a new type of effluent. This calls for in-depth study in the treatment philosophy of the particular effluent and its adaptability with other effluents. This requires Treatability Studies be conducted.

Treatability Studies are conducted to ensure the effectiveness of the treatment philosophy on a specific type of Wastewater.

 

The normal approach is to collect the samples from the sources, its characterization, elucidate the pre-treatment (chemical treatment) methodology, requirement of biological treatment and the tertiary treatment philosophy. Selection of Membrane technology forms a unique approach in Tertiary Treatment philosophies.

The R&D facility at Vadodara is capable of conducting anaerobic and aerobic treatabilities, the best application of membrane technologies.

Facilities are also available to do Treatability Study on a Bench top scale and Pilot plant scale.

Bench top studies offer

• An initial view of the process, using lab pot spot pretreatment steps.
• Analytical work is carried out on raw samples and characterization mapped
• A complete treatment philosophy is formulated based on the raw sample character
• A model is created to check the sustainability of the treatment step on a longer time scale with batch effluent feeding model and continuous effluent acclimatization model. A process design based on the Treatment methodology is formulated. The study is carried out at low cost.
• The Treatability Report is presented to the owner for consideration for further study on a pilot plant scale or scales up to project model.

Pilot plant Treatability model is the next step. The pilot plant studies are made if the effluent characteristics are susceptible to changes or if the loads are largely intermittent. Pilot plant studies are also conducted if the application is large wherein the scale up of bench top treatability study to plant scale can create certain inconsistency in routine operation.

Paramount Limited has all facilities to model and fabricate pilot plants that can be shipped to owner’s site to conduct tests.

“Paramount” also conducts Oxygen Transfer Efficiency (OTE) tests allow plant owners to assess the long term running costs of their aeration systems, and confirm that they have the capacity to meet peak oxygen demands.

Tests can be conducted on a wide range of aeration devices including fine bubble diffused aeration systems, coarse bubble aeration systems, surface aerators, jet aeration systems and venturi style aeration systems.

The test procedure involves measuring dissolved oxygen from near zero to saturation against time, and non linear regression is used to determine the mass transfer coefficient. To achieve near zero dissolved oxygen concentration, the test water is deoxygenated using either nitrogen gas or sodium sulphite, dependent on aeration system type and the practicality of a particular method. The power consumption of the aeration devices is monitored using power monitoring equipment suitable for systems equipped with variable speed drives. It is common to test aeration systems at several duty points to determine the efficiency over the whole operational range of a particular system.

The data provided by these tests includes SOTR (Standard Oxygen Transfer Rate measured in kgO2/hr), SOTE (Standard Oxygen Transfer Efficiency measured as a percentage of the air put into the system) and SAE (Standard Aeration Efficiency measured in kgO2/kWh).

C. Plant Adequacy Test:

Adequacy Studies on existing systems are conducted to establish if the present facility is adequate to treat additional effluent load to the system and also recommending various steps to upgrade units to create sufficiency in the system to treat additional effluent loads.

The R&D division of Paramount Limited has been a dependable partner in conducting Adequacy Study on Water and Wastewater systems and have a team of experienced and highly skilled engineers and technicians for such activities.

The study comprises checks on the following.

• Inspecting the existing facilities and studying the operation of the same at designed load conditions. Samplings conducted to verify the performance.
• Source study on the effluents is made to check if any pre-treatment methodology will be required to take additional loads
• Studies on new effluents that are to be generated are conducted. If pilot trials are in progress, effluent samples are collected and treatability checked with that prevailing in the existing model
• A final report with work sheets, checks and balances and recommendations on upgradations, if required are enumerated and submitted for Owners consideration.

D. Process Performance Audit:

Paramount Limited also provides services on process performance audits on Water and Wastewater treatment plants to evaluate the performance of process units and unit operations.

A team of skilled engineers and technicians study the plant operation and conduct capacity test and sampling of inlet and outlet water/ effluent streams. The samples are taken for detailed analysis.

The final audit report with the worksheets is submitted to the Owner for their further actions.

Dissolved Oxygen (DO) profiling is an important first step into identifying means of improving the energy efficiency of an aeration system.

Dissolved oxygen profiling is conducted in activated sludge plants for a number of potential reasons. Common reasons are to determine aeration dead spots in aeration lanes, back flow of aerated liquor into anoxic zones and the efficiency of tapered aeration systems. Profiles are either conducted over the course of a day, or data can be logged over a period of several days.

Activated sludge plant energy efficiency surveys data log the power consumption of the aeration device over a predetermined period, typically one week. During this period, composite samples are taken of the influent to determine organic loading of the Activated Sludge Plant, and also of the final effluent to determine the level of treatment the system is achieving. Nitrification is also taken into consideration as is nitrate recovery in any anoxic zones.

From this information, the theoretical oxygen demand is calculated for the organic load treated which is then related to the power used by the aeration device to give an in process aeration efficiency measured in kgO2/kWh.
