ZLD treatment system utilizes advanced technological water treatment processes are environmentally friendly and highly reliable. For difficult to-treat wastewaters or for situations where scarcity of water demands water recovery (recycle/ reuse) Zero Liquid Discharge (ZLD) technologies help you achieve environmental compliance, reduce your carbon which eliminates liquid waste by converting it into disposable dry solids and Recover around 95% of your liquid waste for reuse. ZLD treatment process can adopted as advanced waste water treatment constituents to by-products that are more readily biodegradable and reducing overall toxicity , pH , COD , TDS , SS , BOD parameters. Zero Liquid Discharge (ZLD) system is to minimize the volume of liquid waste that requires treatment, while also producing a clean stream suitable for use elsewhere in the plant processes. ZLD capable to reduce the all types of waste water and make it reusable and recyclable further for different applications. As per 10 days analysis of different treatment units concluded as up to 82 % of SS and 28 % COD removal in Primary treatment process , 49 % COD and 86 % BOD in UASB process unit, 96 % of both COD and BOD reduction UF process unit and 99 % of TDS reduction in the RO system . As the final results shows the 99 % TDS, 100 % of both COD and BOD, 98 % of SS and TSS reduced (Removed) make it Zero liquid discharge. The plant was generated high quality water which was suitable to recycle in plant premises and which resulted in reduction of water consumption. This study has been undertaken to investigate the determinants of stock returns in Karachi Stock Exchange (KSE) using two assets pricing models the classical Capital Asset Pricing Model and Arbitrage Pricing Theory model. To test the CAPM market return is used and macroeconomic variables are used to test the APT. The macroeconomic variables include inflation, oil prices, interest rate and exchange rate. For the very purpose monthly time series data has been arranged from Jan 2010 to Dec 2014. The analytical framework contains.
