Stormwater runoff is an important avenue for pollutant transport from impermeable surfaces to surface waters. Consequently, stormwater pollutions require additional treatment processes to achieve water quality goals. Natural sorbents have been demanded and studied for using in water treatment because of their low cost and safety. In this study the use of Acorus Calamus, row Hemp, and procedure Hemp in stormwater treatment was investigated. Results of study in all sorbents with different concentrations and dosage indicated high efficiency to reduce pH. The use of Acorus Calamus for Turbidity, Phosphorus, conductivity and colour resulted increasing amount in different Dosage. In another experiments, using row Hemp, procedure Hemp and Linseed as natural sorbents indicated high efficiency to reduce turbidity of stormwater. Also it is obtained that procedure Hemp has high efficiency to reduce conductivity of stormwater.

Rhytidiadelphus Squarrosus

With the aim to investigate sorption properties of natural sorbent prepared from moss Rhytidiadelphus squarrosus we elucidated biosorption of cationic dyes Malachite green (BG4), Auramine O (BY2) and Thioflavine T (BY1) from aqueous solutions. The removal of dyes by moss biosorbent was found to be rapid at an initial stage and the equilibrium was reached within 1-2 hours. The pseudo-n-order kinetic model was successfully applied to the kinetic data and the order of adsorption reaction was calculated in the range from 1.7 to 2.6. The value of rate constant kn' ranged from 0.001 to 0.039 [min-1]/[μmol/g]1-n. The equilibrium data were fitted to the adsorption isotherms. The Freundlich isotherm was found to represent the measured sorption data of BG4, BY1 and BY2 well. The maximum sorption capacities of moss biomass from single dye solutions calculated by Langmuir equation were 354 μmol/g for BG4, 310 μmol/g for BY1 and 382 μmol/g for BY2. These results showed that the prepared biomass presents low-cost, natural and easy available sorbent which may be potentially used for removal of dyes from environment and also may be an alternative to more costly materials such as activated carbon.
