• OBJECTIVE:

•  To describe a standard operating procedure for collection, detoxification, and disposal of effluent.

• SCOPE:

• This Procedure is applicable for collection, detoxification, and disposal of effluent at {Company Name} {Company Location}.

• RESPONSIBILITY:

• Assistant– SHE.
• In charge – SHE.
• Assistant– Maintenance

• ACCOUNTABILITY:

• QA Manager shall be accountable for Approval & Implementation of SOP.

• PROCEDURE:

• Procedure for collection, detoxification, and disposal of effluent.

• Collect process Effluents in receiving tank from Production through closed pipe lines by gravity.

• Transfer the effluent into deactivation reaction tank through the transfer pump from the collection tank.

• Prepare and keep ready the recommended volume of detoxifying agent (4%sodium hypochlorite solution) in dosing container based on measured effluent volume.

• SHE personnel should use all PPE while performing deactivation activity.

• Add detoxifying solution in required quantity(add 2 liters of 4%sodium hypochlorite solution in to approximately 20liters of liquid waste) into deactivation tank through dosing mechanism and perform detoxification activity in the deactivation tank.

• Keep under maintenance for 48 Hrs. for effective deactivation in the deactivation tank.

• After completion of maintenance period transfer the deactivation /detoxified effluent in to storage tank.

• The detoxified effluent through transfer pump is transferred from storage tanks into Pre- treatment tank at Main ETP for further treatment and disposal.

• Check & ensure the level of the sumps should not cross 3/4^th level of its capacity.

• Preparation of 4% Sodium Hypo Chlorite Solution:

• If Sodium Hypo Chlorite Solution received in the strength of 4 % shall be directly used for the Deactivation Process.

• If Sodium Hypo Chlorite Solution received in the strength of 6% The following procedure shall be   followed:
• To Take 1.3litres of 6% Sodium Hypo Chlorite and add 0.7 Liters of Water to mixed to get 4% Sodium Hypo Chlorite Solution
