Mathematical model for phytoremediation of pulp and paper industry wastewater

 

 

 

 

 

S Kumar, K K Dube & J P N Rai

A mathematical model for studying the phytoremediation potential of water hyacinth (Eichhornia crassipes) against pulp and paper industry effluent is developed and analyzed. Initially, phytoremediation potential increased for short time and then leveled off, resulting into consequent pollutant removal, which enabled to calculate logistic differential equation for developing uninhibited growth model. The model developed is applied to some important physico-chemical parameters (pH, EC, BOD, COD, TSS, TDS, Na and K) of the effluent treated using cost effective phytoremediation technology.

The proficiency testing (PT), a quality control, provides an additional means to ensure quality of laboratory testing results. The primary objective of organizing PT is to assess laboratory's technical competence to perform measurements. This paper describes PT of 11 laboratories, nine accredited by National Accreditation Board for Testing and Calibration of Laboratories (NABL), having best measurement capabilities (< 0.25 % of full-scale pressure) by means of interlaboratory comparison using pressure dial gauge (5-70 MPa) as an artifact. Out of the total 145 measurement results, 86 (59.31%) results were found in good agreement with the results of reference laboratory, NPLI, New Delhi. Overall, results were reasonably good being the first PT for all the participating laboratories. This exercise gives an opportunity to calibration laboratory to demonstrate its technical competence of routine calibration services rendered to clients and to have the measurement traceability to the national metrology institute, NPLI, New Delhi.

Direct determination of iron in titania slag leach liquor using thiocyanate

 

  

 

 

J Mohanty & Pratima Mishra

A spectrophotometric method has been developed for the direct determination of total iron in titania slag leach liquor containing Fe(II), Fe(III), Ti(IV), Ca(II), Mg(II) etc., using thiocyanate as a complexing agent. The iron complex absorbs at the wavelength 474-479nm. Beer-Lambert’s Law obeys within the range of 0.1-0.9mg/ml of iron. Iron determination by the present method, compared with the titrimetric method, shows good agreement.

Different particle sizes (21, 15, 9 nm) of CaCO3 were synthesized by in-situ deposition technique and confirmed by X-ray diffraction method. The nano CaCO3 was added from 0.1 wt % to 0.5 wt % in the styrene butadiene rubber (SBR). Rubber nanocomposties were compounded on two-roll mill and molded in compression molding machine. Mechanical properties such as tensile strength, elongation at break, modulus at 300 % elongation, hardness, specific gravity, swelling index, flame retardency and abrasion resistance were studied. These results were compared with flyash filled SBR. There was an improvement in properties of rubber nanocomposites because of uniform dispersion of nano CaCO3 particles in the matrix that intercalates the rubber chains. Hence degree of crosslinking increases multifold in comparison to commercial CaCO3 and flyash.

Some resin based ecofriendly liquid detergents

 

 

 

 

 

 

 

 

 

S K Kharkate, V Y Karadbhajne & B B Gogte

In this study, efforts were made to replace from detergent the conventional active matter, linear alkyl benzene sulphonate (LABS) formulation by polymeric surfactant (alkyd resin). An ecofriendly alkyd resin polymer based on soybean oil and rosin was synthesized and used with sodium lauryl sulphate (SLS) instead of LABS for detergent formulation. Based on surface tension, detergency and foam volume, prepared compositions are on par or sometimes better than commercial samples even at very low (0.5%) liquid detergent. The proposed compositions can be easily prepared in existing alkyd resin manufacturing plant. An alternative production line was suggested for existing alkyd resin plants in paint industry.

Nimesulide, a COX-2 selective drug, possesses anti-inflammatory and analgesic properties. Moreover, it has low gastro-intestinal and renal toxicity. This paper presents industrially viable, new and improved synthesis of nimesulide starting from o-chloro nitrobenzene. The reaction with triphenyl phosphate yields 2-phenoxy nitrobenzene (90%) followed by reduction and mesylation and finally selective nitration furnishes the drug (85%).

An inexpensive controlled drug infusion system based around 80C85 microprocessor with RAM, EPROM and peripheral interface devices is developed. In this system, the drop rate selection is done by BCD thumb wheel switches from 1 to 99 drops/min, LCD display is used for displaying the parameters settings, number of drops infused and various alarms messages for patient safety and unique drop sensing assembly is incorporated for accurate detection of falling drops in drip chamber. The prototype has been tested successfully on neonates.

Production of fungal cellulases by solid state bioprocessing of groundnut shell wastes

 

Ashish Vyas & Deepak Vyas

 

Groundnut shell was found to be potent inducer of cellulases by Aspergillus terreus, A. nidulans and Trichoderma viride in solid-state fermentation. Combination of A. terreus and Trichoderma viride was best for cellulase production.

Upflow Anaerobic Sludge Blanket (UASB) reactor was investigated for the treatment of low biodegradable composite chemical wastewater, which was complex in nature and has low biodegradability (BOD/COD ratio ~0.32), with high concentrations of sulphate and total dissolved inorganic solids (TDIS). The reactor was operated continuously for 60 days with an actual organic loading rate (OLRactual) of 4.25 kg COD/ m3-d accounting for 37 h of detention time in continuous mode without recirculation at a mesophilic temperature of 29±2oC. At steady state conditions, the reactor resulted in 62% of COD removal efficiency accounting for substrate degradation rate (SDRactual) of 2.6 kg COD/ m3-d. The experimental data demonstrated the applicability of UASB system for treating composite chemical wastewater with low biodegradable nature.

Biosorption of Pb and Zn from pulp and paper industry effluent by water hyacinth (Eichhornia crassipes)

 

 

 

 

 

 

 

 

 

V K Verma, R K Gupta & J P N Rai

Lead and zinc uptake by water hyacinth (Eichhornia crassipes) was studied in the laboratory conditions to investigate a low cost natural aquatic treatment system for pollutant removal from pulp and paper industry effluent. Bioaccumulation of Pb and Zn by water hyacinth was found concentration and duration dependent. The plant possessed ability to neutralize the effluent. It could effectively absorb Pb (0.28-1.39 mg/l, 17.6-80.3%) and Zn (0.26-1.30 mg/l, 16.6-73.4 %) after 20 days of treatment. Metal removal efficiency was found to be maximum (80.3% for Pb; 73.4 % for Zn) at 20 per cent effluent concentration, thus highlighting that phytoremediation could be used along with and/or in some cases as a substitute of expensive cleanup technologies in industrial sector.

This work aims to evaluate the sorbent power of pillared inter layer clay (PILC) for humic acid from aqueous solutions. PILC was prepared from natural bentonite clay with lanthana-alumina mixed oxide pillars and was found to be very effective in removing humic acid from water. Maximum adsorption of 97.3 and 88.8 % took place by PILC (pH 3.0) from an initial concentration of 15.0 and 30.0 mmol/l respectively. Electrolyte (NaCl) compresses the diffuse double layer leading to the increased uptake of humic acid; this also showed that van der Waals attraction is an important part of the interactive forces between humic acid and PILC. Adsorption capacity ‘Qo’ (54.32 mmol/g) and binding constant ‘b’ (0.249 l/mmol) were maximum at 10oC and pH 3.0. About 94.6 % can be recovered from the spent clay using 0.01 M NaOH.
