f. Measure the waste upon disposal at designated intervals, and keep records. Assign a
person to be in charge of treating industrial waste and a person to control the
overall waste disposal process. The controller should take appropriate action when
the measured value does not meet the standards.
g. Educate employees in the importance of these standards and encourage them to
cooperate in implementing them. Set up checkpoints to ensure that proper
procedures are followed, and that data is collected and analysed regularly.
h. Wherever possible minimize waste and recycle waste materials. A Roadmap to Quality 21 Unit 6 - Hygiene and Health 05-87581_unit 6.qxd 01/08/2006 10:52 Page 22 Examples of treatment procedures
3. The following are some examples of procedures that can be used to prevent pollution:
a. Process strong acids and alkaline in a neutralizing tank, and neutralize the chemicals
prior to disposal. Measure the pH potential of hydrogen ions prior to disposal.
b. Use the activated sludge process in an established purification system to purify
wastewater leaving the factory. Use carp (fish) as a biological index to check the
purity level prior to discharge. If the carp dies, the level is too high!
c. Give the disposal of used organic solvents to a licensed disposal agency.
d. Gather paper waste and pass it to a qualified agency for recycling.
Figure 6.5a Treating waste (page 23) Standards for preventing environmental pollution
4. Standards to prevent environmental pollution must, at the very least, follow official
environmental standards, laws, and regulations. If possible they should set even higher
5. The main pollution categories, with their elements, are:
a. Air pollution: The major elements of air pollution are carbon monoxide, sulphur
oxide, nitrogen oxide, and suspended particulate matter (SPM).
b. Water pollution: The main control elements are BOD (biochemical oxygen demand),
COD (chemical oxygen demand), DO (dissolved oxygen; standard at 8.8 mg/litre),
SS (suspended solids).
c. Chemical substances: cadmium, cyanogen, organic phosphorus, lead, chromium (6
valence), arsenic, the mercury family, PCB.
6. Standards for prevention vary dramatically from one industry to another. However it is
important to specify the substances that need to be controlled, if there is any danger that
they will be released. Discussion
The following questions ask you to think about how the ideas in the text could be applied in
your company. Some of the ideas may not be relevant to you. Concentrate on those that are
relevant. Keep notes of your conclusions – you will need them to prepare your action plan
afterwards. Where appropriate ask yourself the RADAR questions.
Note: Always include in your discussion any figures referred to in the text if you feel these
are relevant to your company.
a. Parag. 1. Do you agree that a company has as much responsibility for avoiding
environmental pollution outside the factory as inside? Does your company cause
pollution in the outside environment? What kind? What steps are you taking to
reduce it? How effective are these steps?
b. Parag. 2: Apply the RADAR questions to these eight guidelines.
c. Parag. 3: Are any of the examples of treatment procedures in the text and in Figure
6.5a relevant to your company? Are there any alternative procedures that you could

e. Parag. 5: What substances are used or produced in your company that could be
dangerous to the outside environment? Action plan
Draw up a detailed and concrete proposal for dealing with your company’s industrial waste.
You might like to follow the 6-Point Structure. In your introduction make it clear why this is
important. Alternatively you may choose to prepare one action plan when you have
discussed several texts.
